I bike in the city and suburbs. I worry a lot about being hit by a car. Even if I do everything I can to avoid an accident, a moment’s inattention from a car driver could still hurt or kill me. (In a collision between a quarter-ton car and a 200-lb biker and bike, there’s no question who gets damaged most.) I’m not sure this is a reasonable engineering solution, but what if cars were designed to make such collisions less lethal? Car Airbags That Could Save A Cyclist's Life | Popular Science.
